MUSIC-LEAF TURNER.

Application tiled March 9, 1923. Serial No. 623,936.

To all whom t may concer/n.'

Be it known that I, HERBERT D. COOK, a v citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Im rovements kin a Music-Leaf Turner, o which the following is a specification.

This invention relates to a device for turning music sheets, and has been designed for use'particularly in connection with a piano, but can also be used in connection with music stands for the playing of other musical instruments.

One of the objects of this invention is to provide a device of the character indicated, which will securely hold a piece of sheet music in an operative position on the front of a piano, and which will automatically turn the leaves of the music as the operator presses a key carried'by the device while playing 'one of the regular keys of the piano.

A further object of the invention is to provide a device of the character indicated, whereby the leaves can be automatically returned to their` original position for replayingof the piece, as is very desirable in the use of a student learning to play the piano.

A still furtherv objectof my invention is yto provide a music leaf turner of the above indicated character, which can be adjusted to fit the music leaf support that usually accompanies and forms apart of a piano.

And a Vstill further object of my invention is to provide a music leaf turning device of the character indicated, which is not only ornamental in design and forms an attractive part of the piano, but one that is simple in construction and operation, durable, etticient for the purpose intended, and one that can be manufactured and placed on sale at a low cost.

45 These and like objects of the invention will be better understood as ythe description follows and as is specifically pointed out in the appended claims.

Referring to the accompanyin drawings which form a part of this speciflgcation and which clearly illustrate the construction and operation of my improved music leaf turning device,

Figure l is a front view of a music leaf turner constructed in accordance with my invention.

Figure 2 is a side elevation of same.

' Figure 3 is a front view of my improved music leaf turner with the cover removed to better show the operation of same.

Figure 4 is a top plan view.

Figure 5 is a section taken on line 5-5 of Figure 3, and

Figure 6 is a section taken on line 6-6 of Figure 3.

Referring to the accompanying drawings in detail, like characters will be used to designate like parts in the different views.

In the drawings, the numeral l indicates as a whole my improved music leaf turning device, which comprises a back rest 2, a front plate 3, and a bottom connecting plate 4, also a top connecting plate 5. The bottom connecting plate t is pivotally connected to the back 2 as at 6, the purpose 75 of which will be better vunderstood as the description follows.

Mounted in the top plate 5 intermediate the ends of same is a bolt 7 that extends downwardly a short distance within the hollow space formed by the back rest Q and front plate 3. A pair of curved arms 3 and 9 are loosely mounted on the bolt 't' beneath the top 5, said arms 8 and 9 extending outwardly through a recess formed in the upper edge of the front plate 3. Each of the arms 8 and 9 is provided with a clamp l0 and a rest 11 for each sheet of music. The rests or supports 1l can be of any shape desired. For the purpose of showing my invention, I have made same approximately L-shape.

The lower edge of the front plate 3 is bent at right angles to form a ledge 12 on which the sheet music rests and clips 13 are employed for holding the sheet music or book as the case may be firmly against the face of the front plate byy engaging the binding of same.

Positioned Within the space formed by Y'the front and rear walls are three vertical operating rods 14, 15, and 16. The said rods 14, 15, and 16 are adapted to lay against the back wall 2 and are. held in such position by means of a cross brace 17. The lower edges ofthe members 15, and 16 are bent at right angles to provide keys 18. Each of the members 14, 15, and 16 is formed with a struck out Aportion adjacent the upper end as at 19, and a leaf spring as designated by the numeral 20` is fastened to the back rest 201i its front face, and the end of each leaf springengages thestruck outportion19 so as to hold the members 14,15, and 16 in an upwardly extended position.

A `series of sliding `arms as indicated Vby the numerals 21, 22, and 23 arehorizontally supported lbeneath the top 5', in brackets 24.

A series of L -shaped levers 25 are pivotally lmoimted on the back rest asiat 26. The sliding rods,21, 22, and 23 are connected to one end of the pivoted levers 25 by means 'of -a link 2T The other' end oifeachV ofthe levers25 is connected to theupper end of members 14,15, and 16 by Vnl eansofa pivoted extension arm 2S.

Assumingthat the device is in an assembled position and thata piece of sheet music is supported lon the frontof the device, and that the operator ofthe piano wishes to .turn oyer Vthe yfirst sheet, pressure is applied to the key 4formed on the lowerend ofthe verticalsliding'rod 14. l As the member14moves downwardly againstthe tension of the spring`20, theniember- 25 swingson the pivot 26 causing thehorizontal rod -21-to slide in the brackets 24l to` thefleftof the holder, during which ,in .ovement arecessBO in the rod 21 is disengaged from the pin 31, thus causing` the rod 21 to move upwardly so that ithe lug 29 formed integral therewith and extending at right angles thereto `engages the curved arm 8, thus causing same to swing on the pivot v'l' turning theclamp 10 and support 11 to ythe left of the Vmusic stand..

When desiring toturn the second sheet,

Y pressure is applied to the ke'y18of the verticalslidingrod 1 5, which acts in Ia similar manner on oneofjthe linksl 25v to movethe Y horia ntal sliding rod 22 to the left', during which operation 'al similar lugl 29a engages theV arm 9, bringing same along with the sheet `music to the left yof 'the stand.` To

pass the lug 29-tlle recessBO'Qi-n the rod'21 engages the pin 31, so that the lug 29" 'of the 21" lies below the arm 9, asclearlyj'illustrated v1in'rlfigure 3 of thefdrawingsl. 1'

l Should'both Aofthe rests 11 be to the right of thestand, and it is desired to turn both to the left, pressure is applied on the ,key

Lthe `pivoted `Vlever VVing both to move both of the arms 8 and 9 and the rests 11 along with the sheet of music to the left of the stand.

In order to provide means for permitting the return of the music to its original position, thei'horizontallifk sliding' member 23 is employed, which is pivotally connected to the vertical sliding member 16, through 25, link 27., and arm 28. lVhen pressure is applied to the key 18 of the-im'ember 16, the rod 23 moves to the right of the casing permittingy the lug 32 to engage thearms 8- and 9 moving same to their original position. Y

1n order to provide means wherebythe music leaf 'turner' may be ustedffor engagingpiano'racks o'fjvarious shapes and angles, the devic'ei's provided .with cnnectingrods v33 and 34 on eachv ^sidel thereof, said connecting rods being, adjustably'secured together by means of a boltand wing'nut 35,'5s'oftliat the angleA of the bottom connecting pllit`t`e`f4 may'` be varied witlrielaltioiif t the.`
